01Overview

Dual Delay X is an effects plugin from UVI focused on delay. Its stereo engine is built on unitary rotation and reflection matrices, a approach the developer compares to the feedback networks used in reverbs, but tuned for longer discrete echoes. The result is stereo manipulation of the delayed signal over time. The plugin covers a wide range of styles, from clean delays to heavily colored effects, and it ships with a factory library of presets.

Sound Shaping in the Feedback Path

Dual Delay X places its sound shaping tools inside the feedback path. These include peak, high-cut and low-cut filters, diffusion, dispersion, and digital grit through downsampling and bit-depth reduction. Tape saturation adds warmth and drive. Together these let you control the tone and character of each repeat rather than only the overall delay sound.

UVI says the engine moves easily between warm analog tones and crunchy lo-fi digital sounds, so the same plugin can cover subtle room-style repeats and more aggressive effect design.

Single-Panel Workflow and Presets

All controls sit on one panel. Stereo and phase graphs at the top show the effect over time, and parameters are split between the primary delay on the left and the feedback path on the right. Built-in A/B comparison lets you audition changes against a stored state.

The factory library includes dozens of presets in categories such as Stereo, Mono, Short (Reverbish), Mods and Special FX. Parameter locks on Mix, Time and Feedback keep those settings fixed while you browse presets.
